Materials
Shape programming and morphing in protein-based hydrogels
Dynamic biomaterials with conformational changes can facilitate artificial tissue structures for morphological transformation and soft robotics in order to react and change in response to their environment
Breakthrough in molecular machines
Molecular machines have the potential to revolutionize the future – if we can find a way to control them. Researchers now report that they have found a way to control the small machines so that they move in a certain direction – for example, into the bloodstream
Screw cancer: Microneedle sticks it to cancer tissue
Drug-loaded microrobotic needle effectively targets and remains attached to cancerous tissue in lab experiments without needing continuous application of a magnetic field, allowing more precise drug delivery
Graphite nanoplatelets prevent infections
Nanoplatelets on the surface of implants prevent bacterial infection but, crucially, without damaging healthy human cells
Personalized microrobots swim through biological barriers, deliver drugs to cells
Tiny biohybrid robots on the micrometer scale can swim through the body and deliver drugs to tumors or provide other cargo-carrying functions
Gold nanoparticles uncover amyloid fibrils
Scientists have developed powerful tools to unmask the diversity of amyloid fibrils, which are associated with Alzheimer’s disease and other neurodegenerative disorders
Opening a new chapter in antibody mimetics
A new method to rapidly synthesize and screen libraries of two-dimensional peptoid nanostructures capable of selectively binding target proteins was developed
Scientists program cells to carry out gene-guided construction projects
Researchers have developed a method to genetically reprogram cells to build artificial structures
